Just an FYI regarding an acpi regression affecting some v9.0. Not sure if
we were caught by this or not, but its helpful to know.

Below excerpted from http://www.freebsd.org/cgi/query-pr.cgi?pr=165647

Description9-RELEASE works fine. csup to 9-STABLE and make buildworld
kernel etc gives a system the hangs during the boot process.

There are no error messages during the part boot, and no panic. Last
messages before hang are:

pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0
pci0: <ACPI PCI bus> on pcib0

Fault lies somewhere in:

Edit src/sys/dev/acpica/acpi.c
Add delta 1.305.2.4 2012.02.23.22.26.14 jkim
Edit src/sys/dev/acpica/acpi_ec.c
Add delta 1.95.2.2 2012.02.23.22.26.14 jkim
Edit src/sys/dev/acpica/acpi_hpet.c
Add delta 1.38.2.2 2012.02.23.22.26.14 jkim
Edit src/sys/dev/acpica/acpi_timer.c
Add delta 1.50.2.3 2012.02.23.22.26.14 jkim
Edit src/sys/dev/acpica/acpivar.h
Add delta 1.125.2.4 2012.02.23.22.26.14 jkim

dmesg -v, pciconf, and csup out in attachment (.org structured).
How-To-Repeat
csup to STABLE after 2012.02.23.22.26.30, build, boot.
